Why the new MetroAmp Zero Loss Loop has double face copper PCB? the underside has the ground and the upperside has the connection between components.
I suppose for best grounding isolation , and the upperside has the B+ high voltage. What do you think? Should I upgrade my old loop for the new? Is the new more quiet, less noisy?
Marshalls loop is double face copper also. But has ground on the both sides.
thanks
